l.Applicaetton tiled February Y This invention relates to exhaustI boxes for canueries and has tor' an object toproride a structure adapted to transport lilled cans of goods through a heated chamber for the. purpose kof sterilizing or cooking the contents ot' the cans.

It further object of the invention is to an improved structure for transporting cans through a heated chamber lau'luvardly and forwardly in a zigzag line tofinally discharge the can at the corner e chamber opposite its point of introduction.

A further object of the invention is to provide improved mechanism for carrying ont the aforesaid objects. i

A further objectof the invention is to provide improved means for heating the chamber through which the cans are transported.

A. further object ot the invention is to f-,rovide improved means for reversing thedirection of the cans at each end of the heated chamber.

l-Vith these and other objects in View the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter more -fully described and claimed. c

-The improved exhaust box which forms i the subject matter of this application comprises a chamber 10 composed of side walls 11, end walls 12, bottom 13 and a removable top closurel 14. The top closure is maintained upon the chamber in a substantially steam tight condition in any approved manner as bythe employment ot fingers 15 secured to such cover and with eccentric locks 16 pivot-ally secured by the links 17 to the side Walls 11.

the bottom 1 3 are a plurality of T-irons 18 extending longitudinally of the chamber throughout its entire length with other T- irons 19' Ydisposed between the T-irons 18 and stopping short of the ends as will be hereinafter more ully described. Between the T-irons 18 and 19 channel irons 20 are located in the channel of' which cables 21 sheaves 22 and 23 carried at one end of the chamberupon shaft 24 and atthe opposite end of the chamber over sheaves 25 and 2li carried upon the shaft 27. rihe sheaves 22 at one end and 25 at the opposite end are carried rigidly upon the shafts 2a and 2T respectively while the sheaves 23 at one end and 26 vat the opposite end are free to rotate upon the shafts 24' and 27 respectively. AThe shaft 24 is driven by any approved gearing as shown at 28 and from a pulley 29-being substantially the usual and ordinary form of driving such apparatus. The shaft 27 is driven from the Vshaft 24C by employing a' W'ithin the chamber 1D andspaced above are mounted to move, such cables passing over cables which pass over 'the tight sheaves upo'n both of such shafts will move in opposite 'directions as indicated by the small arrows at the left of Fig. v1.

To facilitate the proper introduction of cans to thechamber one of the cables 33 eX- tends outwardly beyondv the shaftQ/ and passs over a she'ave 311 journaled upon a shaft 35* and receiving power and motion from the shaft 27. To discharge the cans from thechamber a like cable 36 extends beyond the shaft 27 over a sheave 37 and the cable receives motion vtrom the shat't 24.

Itwill `be noted especially from Fig. 5 that the cables extend upwardly above the anges of the channels 20 and also above the flanges ofthe T-irons 18 and 19. By this arrangement acan `which lis shown in dotted lines at 38 in such Fig. 5 would rest uponv the top of the 'cable 2O and only slightl upon either one Aofthe-.lother angesof t e T-irons 18 and 19 so` that as4 `the cables move longitudinally .of the chamber'the cans resting upon such cable will be moved also therewith.` A

To reverse thedirection of movement of the cans at theopposlte ends of'the chamber disks 39 are employed carried upon the up e'r ends of shafts '40 which extend upwar 1y through the bottom 13 of the chamber and are journaled infbearings 41.

Under, the bottom vof the chamber the shafts .40 are provided' with bevel gears 42 intergeared with gears 43 carried uponth'e shafts 44,'the4 shafts being similar at each end of thechamber. The shafts/14 are driven by means of sprockets 45 and sprocket chains 46 from sprockets 47 and 48 carried upon shafts 24 and 27 resp'ec ively.' The d1sks 39 are chamfered at th ir v peripheries so that the cans 38 carried along u on the cables will be moved readil upon t e disks and the disks being rotateV as indicated in Fig. 3 will 'move the 'cans about the extremities ofthe T-irons 19 which extend over the disks substantially to the centers thereof and discharge them between the adjacent T-irons as indicated at'Fig. 3 so that the direction of such cans will be reversed to travel to the opposite end of the chamber.

.To heat the chamber a coil 'of pipe49 is located lin 'thechamber having inlet and outlet connections 50 and 51. It is necessary 'thattheeans being transported through the heated chamber be maintained in a moist condition to prevent the contents of the can from sticking to -the inner surface of the cans. For this purpose\' pipes 52', extend longitudinally of the chamber, perforated to permit the escape of steam and connectedin- 'dependentl-y to laterals 53 which in turn connect with a supply pipe 54.- and controlled by independent valves 55. To maintain the cables 21 taut condition, heavy sheaves 56 are journaled upon arms 57 which are fulcrumed at any convenient point upon the under side of the chamber and bear upon such cables.

In operation it will be apparent that cans will be set upon the cable 33 at the lower left hand corner in Fig. 1 between the ad jacent Tironsand by such cable will be moved into the chamber and longitudinally of such chamber to thc, opposite end where it will be dischargedupon the disk 39 and its direction changed. To provide a proper rotation of the can upon the disk a scalloped member 58 is secured at each end,

the utility of'such strip being shown best.

at Fig. 3. As ythe cans are rotated upon the disk 39 in engagement with such sculloped'member'S they are discharged upon the oppositely traveling cable and are moved to the opposite end of the chamber where their direction of travel is again reversed.

It will be apparentvthat the cans will travel backwardly and forwardly through the chamber` until finally discharged upon the cable 36 which will move them out of the chamber at the upper right-hand corner of Fig. 1 where they maybe removed from the cable and sealed.

We claim 1. In adevice 'of the elass'described, a chamber, channels extending longitudinally of the chamber in spaced relation, cables disposed in the channels, means to move alternate cables in opposite directions, guides disposed upon opposite sides of the channel, and means at opposite ends of the chamber adapted to move an object from one cable to the oppositely traveling adjacent cable.

2. In a-device of the class described, a housing, 'channels extending longitudinally of the housing, cables moving in the channels, alternate cables 'moving in opposite directions, said cables extending sllghtly above the flanges of the channel, guides positioned upon opposite sides of veach of the channels, and means to transfer anobjcct from one cable to the adjacent cable at the completion of travel of `said object upon said cable.

3. In a device of the class described, a plurality of channels, sheaves journaled at the' ends of said channels, cables carried upon the sheaves and moving in the channels, alternate cables moving in opposite directions, the extreme cables extendingv beyond the remaining cables, guides positioned upon opposite sides of the channels and proportioned to support an object upon the tndnally thereof and moved alternately in opposite tlireetionatdisks mounted to rotate in vhorizontal planes located immediately' above the cables, the edges of said disks being tapered substantially to un edge, the opposite sides of said disks moving in the direction of the cable adjacent which it occurs.
